Recent safety warnings from AI leaders including Anthropic's Dario Amodei, OpenAI's Sam Altman, and Elon Musk have heightened scrutiny of large language model capabilities and risks, triggering September 2026 selloffs in Nvidia and other chip stocks while prompting OpenAI to delay its IPO. Traders are weighing massive data center capex against falling token prices, heavy debt loads at hyperscalers like Oracle, and monetization challenges from aggressive API cuts by competitors such as DeepSeek. Upcoming catalysts include Anthropic's planned IPO and potential regulatory or funding developments that could clarify whether infrastructure spending sustains or exposes overvaluation in the sector. Market-implied odds reflect ongoing debate over timing amid these pressures.
